Why is apex locator used?
Apex locators can be used to determine if the perforation communicates with the periodontal membrane, This is based on Sunada’s2 findings that the electrical resistance between the mucous membrane and the periodontium can be considered to have a constant relationship.
What is apex locator?
An electronic apex locator is an electronic device used in endodontics determine the position of the apical constriction and thus determine the length of the root canal space.
How accurate is apex locator?
Conclusion. Based on the findings of this study, all four generations of apex locators under review were found to be accurate in measuring working length. Hence, the generation of an apex locator does not play a significant role in how accurately electronic devices determine working length.
Does apex locator hurt?
Conclusions: There is no difference in postoperative pain between working length measurement methods by using an electronic apex locator or digital radiography.
Who invented apex locator?
Current history would have you believe that the evolution and development of the electronic apex locator for use during root canal procedures emanated from the work of Suzuki in 1942, which was developed as a product by Sunada in 1962.
How do I check my working length with apex locator?
The best working length is found by subtracting approximately 0.5 mm from the length obtained with the apex locator. It is important to know that there is potential for interference of an electronic apex locator with a patient’s cardiac pacemaker function.
What is Apex in dental?
The apex is the bottom part of a tooth’s root. Your teeth have tiny passageways called root canals. An open apex occurs when the root canals are not closed. Open root canals can lead to pulp exposure and infection. Pulp is the soft substance inside of your teeth.
